Conservative surgery for ovarian torsion in young women: perioperative complications and national trends.

ABSTRACT:

Objective

To analyse populational trends and perioperative complications following conservative surgery versus oophorectomy in women <50 years of age with ovarian torsion.

Design

Population-based retrospective observational study.

Setting

Nationwide Inpatient Sample in the USA (2001-2015).

Population

In all, 89 177 ovarian torsions including 20 597 (23.1%) conservative surgeries and 68 580 (76.9%) oophorectomies.

Methods

(1) Trend analysis to assess utilisation of conservative surgery over time, (2) multivariable binary logistic regression to identify independent factors associated with conservative surgery and (3) inverse probability of treatment weighting with a generalised estimating equation to analyze perioperative complications.

Main outcome measures

Trends, characteristics and complications related to conservative surgery.

Results

Performance of conservative surgery increased from 18.9 to 25.1% between 2001 and 2015 (32.8% relative increase, P = 0.001) but decreased steadily after age 15, and sharply declined after age 35 (P < 0.001). On multivariable analysis, younger age exhibited the largest effect size for conservative surgery among the independent factors (adjusted odds ratios 3.39-7.96, P < 0.001). In the weighted model, conservative surgery was associated with an approximately 30% decreased risk of perioperative complications overall (10.0% versus 13.6%, odds ratio 0.73, 95% confidence interval 0.62-0.85, P < 0.001) and was not associated with venous thromboembolism (0.2 versus 0.3%, P = 0.457) or sepsis (0.4 versus 0.3%, P = 0.638).

Conclusion

There has been an increasing utilisation of conservative surgery for ovarian torsion in the USA in recent years. Our study suggests that conservative surgery for ovarian torsion may not be associated with increased perioperative complications.

Project description:BackgroundWomen with ovarian cancer have been shown to be at significant risk of malnutrition with incidence rates described as being between 28% to 67%. Nutrition interventions may improve clinical outcomes positively, nutritional status or quality of life measures in this patient group.ObjectivesThis review was conducted to assess the effects of nutrition interventions during the perioperative period for women with ovarian cancer.Search methodsElectronic searches were conducted of the Cochrane Gynaecological Cancer Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL 2012, Issue 7), Medline (1946 to July week 4 2012), Embase (1980 to 2012 week 31), DARE (to 7th August 2012) AMED (1985 to April 2012), BNI (1992 to April 2012), CINAHL (to April 2012). We also searched trials databases, conference proceedings and related citation lists. Reference listings were handsearched. No restrictions were applied on language or date.Selection criteriaRandomised controlled trials (RCTs) in which women 18 years and over with any stage of ovarian cancer, including recurrent cancer, were in the perioperative phase of treatment and received any type of nutrition intervention.Data collection and analysisTitles and abstracts were screened by two review authors with study selection discussed by a team. Pairs of review authors worked independently on data collection and compared findings.Main resultsA total of 4092 titles were screened and 14 full text reports reviewed; a single small study met the inclusion criteria. In the included RCT, 40 women (35 with ovarian cancer) had extensive elective surgery including bowel resection for treatment of gynaecological malignancy. Randomisation was made to either early oral feeding (oral fluids in the first 24 hours, solid foods on the following day) or to a 'traditional' feeding regimen where oral fluids and foods were delayed until there was evidence of bowel function. Most women in the early feeding group (14/18) were able to resume eating solid food one day after surgery. This resulted in a significantly shorter hospital stay with no increase in postoperative complications or change in quality of life measures in comparison with the women on the 'traditional' feeding regimen. The incidence of nausea and vomiting during the postoperative stay was similar in both groups and was noted in slightly more than half of the women. Overall survival was evaluated until 30 days following discharge from hospital; in this period, there was one death of a woman who had been in the 'traditional oral feeding' group, cause of death was not noted. We assessed risk of bias and found no high risk of bias was identified in the methodology and reporting of the included study, although there was an increased risk of bias due to the small size of the study in which not all of the women had ovarian cancer.Authors' conclusionsAlthough women with ovarian cancer have been shown to be at risk of malnutrition, there is a lack of evidence derived from RCTs evaluating the identification, assessment and treatment of malnutrition during the perioperative phase of treatment. There is evidence from one small study that some women with ovarian cancer undergoing surgery with associated bowel resection may safely commence oral fluids within 24 hours of surgery and solid foods on the following day. Further research is required, including a RCT, to generate guidance concerning the treatment of malnutrition in this patient group.
